I wanted to do the Giro de Rigo with a buddy and while we both did the same route and event, he was only on my screen maybe 3 times in 2 hours. Lots of other people in the chat reporting the same thing. People dropping in and out, draft disappearing etc.
It was a pity as we were psyched to ride it together at the beginning.
I was on a Garmin ride the other day and i had the same thing. I rode for an hour mostly on my own, i would see people in the distance sporadically but they would disappear before i could catch them. There were 800 riders apparently and i’m not sure what went wrong.
